Function/Subroutine Documentation

   integer function izmax1 (integer N, complex*16, dimension(*) ZX, integer INCX)
       IZMAX1 finds the index of the first vector element of maximum absolute value.

       Purpose:

            IZMAX1 finds the index of the first vector element of maximum absolute value.

            Based on IZAMAX from Level 1 BLAS.
            The change is to use the 'genuine' absolute value.

       Parameters:
           N

                     N is INTEGER
                     The number of elements in the vector ZX.

           ZX

                     ZX is COMPLEX*16 array, dimension (N)
                     The vector ZX. The IZMAX1 function returns the index of its first
                     element of maximum absolute value.

           INCX

                     INCX is INTEGER
                     The spacing between successive values of ZX.  INCX >= 1.
